    230v for mobile minisplit

    Thanks! If I go genset will definitely investigate. Still like single fuel but propane may be better than gasoline.

    230v for mobile minisplit

    Makes a lot sense. If I had the generator already, the math might be different. I want to see how far I can push without a generator - with fallback go without AC or use the 200a 24v alternator. Rationale on generator is that I'd like to stay single fuel and diesel gensets are $$.

    230v for mobile minisplit

    Thanks. While it seems like I might be able to get a NA minisplit to run with EU230 power, I think it opens too many cans of worms (e.g., any warranty is shot, could be trouble if I sell etc.) But the engineer and HAM in me really wants to try it.

    230v for mobile minisplit

    I'm thinking 28-31. They cost and extra 500-600, but consume 25-30% less power. That is pretty reasonable when you think of how much less you have to spend on the power side.

    230v for mobile minisplit

    I think I am am beginning to understand. Summary below. Here is the installation instructions for the NA model: As Supervstech notes, there is no neutral - just L1 & L2- & blower looks 230 as well. The L1 & L2 would show ~220-240 in NA residential. Curious what S3 is? Control? Here is...

    230v for mobile minisplit

    I was looking at the Mitsubishi. https://hvacdirect.com/hvac/pdf/M-FH_Condenser_Install.pdf They show L1 & L2 120v leads. Didn't see anything that show a single 230v approach.

    230v for mobile minisplit

    Thanks! I think you are right. You'd need a 230v split phase inverter for option 1] for any mini-split designed for the US market. And I don't want to think about importing a minisplit. While there are a number of 230v split phase inverters on the market, pretty sure the Phoenix 230v listed...

    230v for mobile minisplit

    Thanks! That's kinka what I was going for with option 1]. You can go with different price points depending on efficiency. I think this is the cleanest approach and probably the most efficient - especially in the winter when charging times are short and I'll probably be using diesel heat vs...

    Thanks appreciate the thoughts and for how #2 would actually work.

    230v for mobile minisplit

    HI, After a lot of debate, we're planning to go with a high SEER minisplit for our rig. Seems like it is cheaper to buy a higher efficiency unit than a larger power system(and we running short of room for panels). But....the high SEER units are almost all 208/203 single phase. Looked at a...

    Solar charger & Shore power

    Thanks! Not sure I follow. Are you saying a) regardless of approach you need some form of state-of-charge monitor, b) that really you need go with option 1) or, c) something else? Thanks again

    Solar charger & Shore power

    Hi, I'm a bit confused about if multiple charges need to be coordinated (e.g., solar, shore, generator) Looks like there are a number of approaches from different companies and in different wiring diagrams: 1) The Samlex inverter/chargers looks like they want you to run the output of the...

    Splitting EV OEM batteries to lower voltages

    I like the power density and price of the used EV batteries. However, because of constraints on the layout and count of the solar panels, I am looking at an open voltage of ~40v (2x 12v panels in series). So I'd need to split most of the EV battery options into shorter chains. In a extreme...
